What I have seen from the Gracie video's is that when a Trained martial artist is up against one of the Gracies, they seem to lose all of their teachings. One video I saw was BJJ against a Hapkido black belt. Gracie rushed in with his arm extended, and the dude runs backwards. I would have pivoted away ended up at the side and thrown with kotegaeshi or Hiji. I think in our dojo's we should train more against such attacks. BJJ is a fast growing sport, we need to revise the way we train, Start defending against grappling and punches, and stop focusing on wrist grabs.
